When a guy is turned on, but not quite ready to grab a couch pillow to awkwardly conceal his arousal- an erection that is safe for public consumption- i.e. not pitching a tent, but beginning to feel aroused.
When that girl with that fine ass bent over right in front of me to adjust the spoke nipples on her Fuji bicycle, I chubbed up a bit.
